- High-Quality Material: Our hollow metal anchors are crafted from durable carbon steel with a galvanised finish. This ensures exceptional strength and resistance to deformation, making them reliable for long-term use. - Enhanced Fastening Power: Featuring a unique petal nut expansion design, these anchors expand outward when the screw is tightened. This increases the holding force, ensuring that attached elements remain secure and stable, making them ideal for thin plates. - Simple Installation: The installation process is straightforward. Insert the anchor bolt into the pre-drilled hole, then place the screw into the anchor. Use a rivet tool or wrench to pull the screw outward until the anchor forms a petal shape against the plate. Finally, use a screwdriver to secure the screws and the attached material. - Comprehensive Assortment: Each package includes 60 hollow wall anchors in varying sizes: 20 x M4 x 20 mm, 20 x M5 x 25 mm, and 20 x M6 x 25 mm.
